ABSTRACT

An electronic device with a touch-sensitive display and one or more sensors to detect signals from a stylus associated with the device: displays a user interface in a viewing mode, the user interface including a content region and a first control region; while displaying the user interface in the viewing mode, detects an input by a first contact on the touch-sensitive display; and, in response to detecting the input: when the first contact is a stylus contact in the content region: changes from the viewing mode to an editing mode; and displays, in the content region, a mark drawn in accordance with movement of the first contact; and when the first contact is a non-stylus contact in the content region: remains in the viewing mode; and performs a navigation operation in the content region in accordance with movement of the first contact without displaying the mark.

RELATED APPLICATIONS

This application claims priority to U.S. Provisional Application Ser. No. 62/349,063, filed Jun. 12, 2016, entitled “Devices and Methods for Manipulating User Interfaces with Stylus and Non-Stylus Contacts,” which is incorporated by reference herein in its entirety.

TECHNICAL FIELD

This relates generally to electronic devices with touch-sensitive surfaces, including but not limited to electronic devices with touch-sensitive surfaces that manipulate user interfaces with stylus and non-stylus contacts.

BACKGROUND

The use of touch-sensitive surfaces as input devices for computers and other electronic computing devices has increased significantly in recent years. Exemplary touch-sensitive surfaces include touchpads and touch-screen displays. Such surfaces are widely used to manipulate user interface objects on a display.

User interfaces can be manipulated with either finger or stylus inputs. Finger inputs are more common than stylus inputs, in part because conventional methods that use styluses are cumbersome and inefficient.

SUMMARY

Accordingly, disclosed herein are electronic devices with faster, more efficient methods for manipulating user interfaces in applications (e.g., an application that views and edits images and Portable Document Files (PDFs), such as Preview from Apple Inc. of Cupertino, Calif.) with stylus and non-stylus contacts. Such methods optionally complement or replace conventional methods for manipulating user interfaces with stylus and non-stylus contacts. Such methods reduce the number, extent, and/or nature of the inputs from a user and produce a more efficient human-machine interface. For battery-operated devices, such methods conserve power and increase the time between battery charges.

The above deficiencies and other problems associated with user interfaces for electronic devices with touch-sensitive surfaces are reduced or eliminated by the disclosed devices. In some embodiments, the device is a desktop computer. In some embodiments, the device is portable (e.g., a notebook computer, tablet computer, or handheld device). In some embodiments, the device has a touchpad. In some embodiments, the device has a touch-sensitive display (also known as a “touch screen” or “touch-screen display”). In some embodiments, the device has a graphical user interface (GUI), one or more processors, memory and one or more modules, programs or sets of instructions stored in the memory for performing multiple functions. In some embodiments, the user interacts with the GUI primarily through stylus and/or finger contacts and gestures on the touch-sensitive surface. In some embodiments, the functions optionally include image editing, drawing, presenting, word processing, website creating, disk authoring, spreadsheet making, game playing, telephoning, video conferencing, e-mailing, instant messaging, workout support, digital photographing, digital videoing, web browsing, digital music playing, and/or digital video playing. Executable instructions for performing these functions are, optionally, included in a non-transitory computer readable storage medium or other computer program product configured for execution by one or more processors. Executable instructions for performing these functions are, optionally, included in a transitory computer readable medium or other computer program product configured for execution by one or more processors.

In accordance with some embodiments, a method is performed at an electronic device with a touch-sensitive display, the device including one or more sensors to detect signals from a stylus associated with the device. The method includes: displaying a user interface in a viewing mode on the touch-sensitive display, the user interface including a content region and a first control region; while displaying the user interface in the viewing mode, detecting an input by a first contact on the touch-sensitive display; and, in response to detecting the input: in accordance with a determination that the first contact is a stylus contact in the content region: changing from the viewing mode to an editing mode, distinct from the viewing mode, that is configured to enable drawing on the content region in the user interface; and displaying, in the content region, a mark drawn in accordance with movement of the first contact in the input; in accordance with a determination that the first contact is a non-stylus contact in the content region: remaining in the viewing mode; and performing a navigation operation in the content region in accordance with movement of the first contact in the input without displaying the mark that corresponds to the first contact in the content region; in accordance with a determination that the first contact is a stylus contact in the first control region, performing a control operation; and in accordance with a determination that the first contact is a non-stylus contact in the first control region, performing the control operation.

DESCRIPTION OF EMBODIMENTS

Many electronic devices have an application that views and edits images and Portable Document Files (PDFs). Some of these applications allow a user to annotate a PDF document (e.g., with marks, highlighting, notes, etc.) and also allow the user to navigate within the document (e.g., scrolling up and/or down in the document). However, existing methods for annotating and navigating in PDF documents are slow and inefficient. For example, the user may need to activate a drawing affordance before being able to annotate a document. Further, the user may need to activate a viewing affordance (or alternatively, to deactivate the drawing affordance) before being able to navigate within the document. Further, in conventional methods, stylus contacts and non-stylus contacts are used interchangeably and are not able to serve different roles. The embodiments below address these problems by providing a method that allows simultaneous annotation with a stylus contact and navigation with a non-stylus contact (e.g., a finger) without having to activate a mode-change affordance.

Below, FIGS. 1A-1B, 2, 3, 4, 5A-5B, and 6A-6B provide a description of exemplary devices. FIGS. 7A-7R illustrate exemplary user interfaces for viewing and editing documents with stylus and finger inputs. FIGS. 8A-8D are flow diagrams illustrating a method of viewing and editing documents with stylus and finger inputs. The user interfaces in FIGS. 7A-7R are used to illustrate the processes in FIGS. 8A-8D.

Exemplary Devices

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the various described embodiments. However, it will be apparent to one of ordinary skill in the art that the various described embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.

It will also be understood that, although the terms first, second, etc. are, in some instances, used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first contact could be termed a second contact, and, similarly, a second contact could be termed a first contact, without departing from the scope of the various described embodiments. The first contact and the second contact are both contacts, but they are not the same contact, unless the context clearly indicates otherwise.

The terminology used in the description of the various described embodiments herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description of the various described embodiments and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

As used herein, the term “if” is, optionally, construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” is, optionally, construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context.

Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Exemplary embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif. Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch-screen displays and/or touchpads), are, optionally, used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch-screen display and/or a touchpad).

In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device optionally includes one or more other physical user-interface devices, such as a physical keyboard, a mouse and/or a joystick.

The device typically supports a variety of applications, such as one or more of the following: a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application.

The various applications that are executed on the device optionally use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device are, optionally, adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device optionally supports the variety of applications with user interfaces that are intuitive and transparent to the user.

Attention is now directed toward embodiments of portable devices with touch-sensitive displays. FIG. 1A is a block diagram illustrating portable multifunction device 100 with touch-sensitive display system 112 in accordance with some embodiments. Touch-sensitive display system 112 is sometimes called a “touch screen” for convenience, and is sometimes simply called a touch-sensitive display. Device 100 includes memory 102 (which optionally includes one or more computer readable storage mediums), memory controller 120, one or more processing units (CPUs) 122, peripherals interface 118, RF circuitry 108, audio circuitry 110, speaker 111, microphone 113, input/output (I/O) subsystem 106, other input or control devices 116, and external port 124. Device 100 optionally includes one or more optical sensors 164. Device 100 optionally includes one or more intensity sensors 165 for detecting intensity of contacts on device 100 (e.g., a touch-sensitive surface such as touch-sensitive display system 112 of device 100). Device 100 optionally includes one or more tactile output generators 163 for generating tactile outputs on device 100 (e.g., generating tactile outputs on a touch-sensitive surface such as touch-sensitive display system 112 of device 100 or touchpad 355 of device 300). These components optionally communicate over one or more communication buses or signal lines 103.

As used in the specification and claims, the term “tactile output” refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user's sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user's hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a “down click” or “up click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as an “down click” or “up click” even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user's movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as “roughness” of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an “up click,” a “down click,” “roughness”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user.

It should be appreciated that device 100 is only one example of a portable multifunction device, and that device 100 optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in FIG. 1A are implemented in hardware, software, firmware, or a combination thereof, including one or more signal processing and/or application specific integrated circuits.

Memory 102 optionally includes high-speed random access memory and optionally also includes non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Access to memory 102 by other components of device 100, such as CPU(s) 122 and the peripherals interface 118, is, optionally, controlled by memory controller 120.

Peripherals interface 118 can be used to couple input and output peripherals of the device to CPU(s) 122 and memory 102. The one or more processors 122 run or execute various software programs and/or sets of instructions stored in memory 102 to perform various functions for device 100 and to process data.

In some embodiments, peripherals interface 118, CPU(s) 122, and memory controller 120 are, optionally, implemented on a single chip, such as chip 104. In some other embodiments, they are, optionally, implemented on separate chips.

RF (radio frequency) circuitry 108 receives and sends RF signals, also called electromagnetic signals. RF circuitry 108 converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals. RF circuitry 108 optionally includes well-known circuitry for performing these functions, including but not limited to an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, a subscriber identity module (SIM) card, memory, and so forth. RF circuitry 108 optionally communicates with networks, such as the Internet, also referred to as the World Wide Web (WWW), an intranet and/or a wireless network, such as a cellular telephone network, a wireless local area network (LAN) and/or a metropolitan area network (MAN), and other devices by wireless communication. The wireless communication optionally uses any of a plurality of communications standards, protocols and technologies, including but not limited to Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), high-speed downlink packet access (HSDPA), high-speed uplink packet access (HSUPA), Evolution, Data-Only (EV-DO), HSPA, HSPA+, Dual-Cell HSPA (DC-HSPDA), long term evolution (LTE), near field communication (NFC), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11ac, IEEE 802.11ax, IEEE 802.11b, IEEE 802.11g and/or IEEE 802.11n), voice over Internet Protocol (VoIP), Wi-MAX, a protocol for e-mail (e.g., Internet message access protocol (IMAP) and/or post office protocol (POP)), instant messaging (e.g., extensible messaging and presence protocol (XMPP), Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE), Instant Messaging and Presence Service (IMPS)), and/or Short Message Service (SMS), or any other suitable communication protocol, including communication protocols not yet developed as of the filing date of this document.

Audio circuitry 110, speaker 111, and microphone 113 provide an audio interface between a user and device 100. Audio circuitry 110 receives audio data from peripherals interface 118, converts the audio data to an electrical signal, and transmits the electrical signal to speaker 111. Speaker 111 converts the electrical signal to human-audible sound waves. Audio circuitry 110 also receives electrical signals converted by microphone 113 from sound waves. Audio circuitry 110 converts the electrical signal to audio data and transmits the audio data to peripherals interface 118 for processing. Audio data is, optionally, retrieved from and/or transmitted to memory 102 and/or RF circuitry 108 by peripherals interface 118. In some embodiments, audio circuitry 110 also includes a headset jack (e.g., 212, FIG. 2). The headset jack provides an interface between audio circuitry 110 and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone).

I/O subsystem 106 couples input/output peripherals on device 100, such as touch-sensitive display system 112 and other input or control devices 116, with peripherals interface 118. I/O subsystem 106 optionally includes display controller 156, optical sensor controller 158, intensity sensor controller 159, haptic feedback controller 161, and one or more input controllers 160 for other input or control devices. The one or more input controllers 160 receive/send electrical signals from/to other input or control devices 116. The other input or control devices 116 optionally include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s) 160 are, optionally, coupled with any (or none) of the following: a keyboard, infrared port, USB port, stylus, and/or a pointer device such as a mouse. The one or more buttons (e.g., 208, FIG. 2) optionally include an up/down button for volume control of speaker 111 and/or microphone 113. The one or more buttons optionally include a push button (e.g., 206, FIG. 2).

Touch-sensitive display system 112 provides an input interface and an output interface between the device and a user. Display controller 156 receives and/or sends electrical signals from/to touch-sensitive display system 112. Touch-sensitive display system 112 displays visual output to the user. The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output corresponds to user-interface objects.

Touch-sensitive display system 112 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic/tactile contact. Touch-sensitive display system 112 and display controller 156 (along with any associated modules and/or sets of instructions in memory 102) detect contact (and any movement or breaking of the contact) on touch-sensitive display system 112 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on touch-sensitive display system 112. In an exemplary embodiment, a point of contact between touch-sensitive display system 112 and the user corresponds to a finger of the user or a stylus.

Touch-sensitive display system 112 optionally uses LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies are used in other embodiments. Touch-sensitive display system 112 and display controller 156 optionally detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch-sensitive display system 112. In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone®, iPod Touch®, and iPad® from Apple Inc. of Cupertino, Calif.

Touch-sensitive display system 112 optionally has a video resolution in excess of 100 dpi. In some embodiments, the touch screen video resolution is in excess of 400 dpi (e.g., 500 dpi, 800 dpi, or greater). The user optionally makes contact with touch-sensitive display system 112 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, device 100 optionally includes a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad is, optionally, a touch-sensitive surface that is separate from touch-sensitive display system 112 or an extension of the touch-sensitive surface formed by the touch screen.

Device 100 also includes power system 162 for powering the various components. Power system 162 optionally includes a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

Device 100 optionally also includes one or more optical sensors 164. FIG. 1A shows an optical sensor coupled with optical sensor controller 158 in I/O subsystem 106. Optical sensor(s) 164 optionally include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor(s) 164 receive light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with imaging module 143 (also called a camera module), optical sensor(s) 164 optionally capture still images and/or video. In some embodiments, an optical sensor is located on the back of device 100, opposite touch-sensitive display system 112 on the front of the device, so that the touch screen is enabled for use as a viewfinder for still and/or video image acquisition. In some embodiments, another optical sensor is located on the front of the device so that the user's image is obtained (e.g., for selfies, for videoconferencing while the user views the other video conference participants on the touch screen, etc.).

Device 100 optionally also includes one or more contact intensity sensors 165. FIG. 1A shows a contact intensity sensor coupled with intensity sensor controller 159 in I/O subsystem 106. Contact intensity sensor(s) 165 optionally include one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a touch-sensitive surface). Contact intensity sensor(s) 165 receive contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system 112). In some embodiments, at least one contact intensity sensor is located on the back of device 100, opposite touch-screen display system 112 which is located on the front of device 100.

Device 100 optionally also includes one or more proximity sensors 166. FIG. 1A shows proximity sensor 166 coupled with peripherals interface 118. Alternately, proximity sensor 166 is coupled with input controller 160 in I/O subsystem 106. In some embodiments, the proximity sensor turns off and disables touch-sensitive display system 112 when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call).

Device 100 optionally also includes one or more tactile output generators 163. FIG. 1A shows a tactile output generator coupled with haptic feedback controller 161 in I/O subsystem 106. Tactile output generator(s) 163 optionally include one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Tactile output generator(s) 163 receive tactile feedback generation instructions from haptic feedback module 133 and generates tactile outputs on device 100 that are capable of being sensed by a user of device 100. In some embodiments, at least one tactile output generator is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system 112) and, optionally, generates a tactile output by moving the touch-sensitive surface vertically (e.g., in/out of a surface of device 100) or laterally (e.g., back and forth in the same plane as a surface of device 100). In some embodiments, at least one tactile output generator sensor is located on the back of device 100, opposite touch-sensitive display system 112, which is located on the front of device 100.

Device 100 optionally also includes one or more accelerometers 167, gyroscopes 168, and/or magnetometers 169 (e.g., as part of an inertial measurement unit (IMU)) for obtaining information concerning the position (e.g., attitude) of the device. FIG. 1A shows sensors 167, 168, and 169 coupled with peripherals interface 118. Alternately, sensors 167, 168, and 169 are, optionally, coupled with an input controller 160 in I/O subsystem 106. In some embodiments, information is displayed on the touch-screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device 100 optionally includes a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location of device 100.

In some embodiments, the software components stored in memory 102 include operating system 126, communication module (or set of instructions) 128, contact/motion module (or set of instructions) 130, position module (or set of instructions) 131, graphics module (or set of instructions) 132, haptic feedback module (or set of instructions) 133, text input module (or set of instructions) 134, Global Positioning System (GPS) module (or set of instructions) 135, and applications (or sets of instructions) 136. Furthermore, in some embodiments, memory 102 stores device/global internal state 157, as shown in FIGS. 1A and 3. Device/global internal state 157 includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch-sensitive display system 112; sensor state, including information obtained from the device's various sensors and other input or control devices 116; and location and/or positional information concerning the device's location and/or attitude.

Operating system 126 (e.g., iOS, Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

Communication module 128 facilitates communication with other devices over one or more external ports 124 and also includes various software components for handling data received by RF circuitry 108 and/or external port 124. External port 124 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used in some iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif. In some embodiments, the external port is a Lightning connector that is the same as, or similar to and/or compatible with the Lightning connector used in some iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif.

Contact/motion module 130 optionally detects contact with touch-sensitive display system 112 (in conjunction with display controller 156) and other touch-sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module 130 includes software components for performing various operations related to detection of contact (e.g., by a finger or by a stylus), such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module 130 receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts or stylus contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts and/or stylus contacts). In some embodiments, contact/motion module 130 and display controller 156 detect contact on a touchpad.

Contact/motion module 130 optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (lift off) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (lift off) event. Similarly, tap, swipe, drag, and other gestures are optionally detected for a stylus by detecting a particular contact pattern for the stylus.

Position module 131, in conjunction with accelerometers 167, gyroscopes 168, and/or magnetometers 169, optionally detects positional information concerning the device, such as the device's attitude (roll, pitch, and/or yaw) in a particular frame of reference. Position module 130 includes software components for performing various operations related to detecting the position of the device and detecting changes to the position of the device. In some embodiments, position module 131 uses information received from a stylus being used with the device to detect positional information concerning the stylus, such as detecting the positional state of the stylus relative to the device and detecting changes to the positional state of the stylus.

Graphics module 132 includes various known software components for rendering and displaying graphics on touch-sensitive display system 112 or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast or other visual property) of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including without limitation text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations and the like.

Haptic feedback module 133 includes various software components for generating instructions used by tactile output generator(s) 163 to produce tactile outputs at one or more locations on device 100 in response to user interactions with device 100.

Text input module 134, which is, optionally, a component of graphics module 132, provides soft keyboards for entering text in various applications (e.g., contacts 137, e-mail 140, IM 141, browser 147, and any other application that needs text input).

GPS module 135 determines the location of the device and provides this information for use in various applications (e.g., to telephone 138 for use in location-based dialing, to camera 143 as picture/video metadata, and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).

Each of the above identified modules and applications correspond to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules are, optionally, combined or otherwise re-arranged in various embodiments. In some embodiments, memory 102 optionally stores a subset of the modules and data structures identified above. Furthermore, memory 102 optionally stores additional modules and data structures not described above.

In some embodiments, device 100 is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device 100, the number of physical input control devices (such as push buttons, dials, and the like) on device 100 is, optionally, reduced.

The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device 100 to a main, home, or root menu from any user interface that is displayed on device 100. In such embodiments, a “menu button” is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad.

FIG. 1B is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory 102 (in FIGS. 1A) or 370 (FIG. 3) includes event sorter 170 (e.g., in operating system 126) and a respective application 136-1 (e.g., any of the aforementioned applications 136, 137-155, 380-390).

Event sorter 170 receives event information and determines the application 136-1 and application view 191 of application 136-1 to which to deliver the event information. Event sorter 170 includes event monitor 171 and event dispatcher module 174. In some embodiments, application 136-1 includes application internal state 192, which indicates the current application view(s) displayed on touch-sensitive display system 112 when the application is active or executing. In some embodiments, device/global internal state 157 is used by event sorter 170 to determine which application(s) is (are) currently active, and application internal state 192 is used by event sorter 170 to determine application views 191 to which to deliver event information.

In some embodiments, application internal state 192 includes additional information, such as one or more of: resume information to be used when application 136-1 resumes execution, user interface state information that indicates information being displayed or that is ready for display by application 136-1, a state queue for enabling the user to go back to a prior state or view of application 136-1, and a redo/undo queue of previous actions taken by the user.

Event monitor 171 receives event information from peripherals interface 118. Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display system 112, as part of a multi-touch gesture). Peripherals interface 118 transmits information it receives from I/O subsystem 106 or a sensor, such as proximity sensor 166, accelerometer(s) 167, gyroscope(s) 168, magnetometer(s) 169, and/or microphone 113 (through audio circuitry 110). Information that peripherals interface 118 receives from I/O subsystem 106 includes information from touch-sensitive display system 112 or a touch-sensitive surface.

In some embodiments, event monitor 171 sends requests to the peripherals interface 118 at predetermined intervals. In response, peripherals interface 118 transmits event information. In other embodiments, peripheral interface 118 transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration).

In some embodiments, event sorter 170 also includes a hit view determination module 172 and/or an active event recognizer determination module 173.

Hit view determination module 172 provides software procedures for determining where a sub-event has taken place within one or more views, when touch-sensitive display system 112 displays more than one view. Views are made up of controls and other elements that a user can see on the display.

Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected optionally correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected is, optionally, called the hit view, and the set of events that are recognized as proper inputs are, optionally, determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture.

Hit view determination module 172 receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module 172 identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (i.e., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module, the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view.

Active event recognizer determination module 173 determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module 173 determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module 173 determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views.

Event dispatcher module 174 dispatches the event information to an event recognizer (e.g., event recognizer 180). In embodiments including active event recognizer determination module 173, event dispatcher module 174 delivers the event information to an event recognizer determined by active event recognizer determination module 173. In some embodiments, event dispatcher module 174 stores in an event queue the event information, which is retrieved by a respective event receiver module 182.

In some embodiments, operating system 126 includes event sorter 170. Alternatively, application 136-1 includes event sorter 170. In yet other embodiments, event sorter 170 is a stand-alone module, or a part of another module stored in memory 102, such as contact/motion module 130.

In some embodiments, application 136-1 includes a plurality of event handlers 190 and one or more application views 191, each of which includes instructions for handling touch events that occur within a respective view of the application's user interface. Each application view 191 of the application 136-1 includes one or more event recognizers 180. Typically, a respective application view 191 includes a plurality of event recognizers 180. In other embodiments, one or more of event recognizers 180 are part of a separate module, such as a user interface kit (not shown) or a higher level object from which application 136-1 inherits methods and other properties. In some embodiments, a respective event handler 190 includes one or more of: data updater 176, object updater 177, GUI updater 178, and/or event data 179 received from event sorter 170. Event handler 190 optionally utilizes or calls data updater 176, object updater 177 or GUI updater 178 to update the application internal state 192. Alternatively, one or more of the application views 191 includes one or more respective event handlers 190. Also, in some embodiments, one or more of data updater 176, object updater 177, and GUI updater 178 are included in a respective application view 191.

A respective event recognizer 180 receives event information (e.g., event data 179) from event sorter 170, and identifies an event from the event information. Event recognizer 180 includes event receiver 182 and event comparator 184. In some embodiments, event recognizer 180 also includes at least a subset of: metadata 183, and event delivery instructions 188 (which optionally include sub-event delivery instructions).

Event receiver 182 receives event information from event sorter 170. The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch, the event information optionally also includes speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device.

Event comparator 184 compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator 184 includes event definitions 186. Event definitions 186 contain definitions of events (e.g., predefined sequences of sub-events), for example, event 1 (187-1), event 2 (187-2), and others. In some embodiments, sub-events in an event 187 include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event 1 (187-1) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first lift-off (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second lift-off (touch end) for a predetermined phase. In another example, the definition for event 2 (187-2) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive sensitive display system 112, and lift-off of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers 190.

In some embodiments, event definition 187 includes a definition of an event for a respective user-interface object. In some embodiments, event comparator 184 performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display system 112, when a touch is detected on touch-sensitive display system 112, event comparator 184 performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler 190, the event comparator uses the result of the hit test to determine which event handler 190 should be activated. For example, event comparator 184 selects an event handler associated with the sub-event and the object triggering the hit test.

In some embodiments, the definition for a respective event 187 also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer's event type.

When a respective event recognizer 180 determines that the series of sub-events do not match any of the events in event definitions 186, the respective event recognizer 180 enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture.

In some embodiments, a respective event recognizer 180 includes metadata 183 with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate how event recognizers interact, or are enabled to interact, with one another. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy.

In some embodiments, a respective event recognizer 180 activates event handler 190 associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer 180 delivers event information associated with the event to event handler 190. Activating an event handler 190 is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer 180 throws a flag associated with the recognized event, and event handler 190 associated with the flag catches the flag and performs a predefined process.

In some embodiments, event delivery instructions 188 include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process.

In some embodiments, data updater 176 creates and updates data used in application 136-1. For example, data updater 176 updates the telephone number used in contacts module 137, or stores a video file used in video player module 145. In some embodiments, object updater 177 creates and updates objects used in application 136-1. For example, object updater 177 creates a new user-interface object or updates the position of a user-interface object. GUI updater 178 updates the GUI. For example, GUI updater 178 prepares display information and sends it to graphics module 132 for display on a touch-sensitive display.

In some embodiments, event handler(s) 190 includes or has access to data updater 176, object updater 177, and GUI updater 178. In some embodiments, data updater 176, object updater 177, and GUI updater 178 are included in a single module of a respective application 136-1 or application view 191. In other embodiments, they are included in two or more software modules.

It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices 100 with input-devices, not all of which are initiated on touch screens. For example, mouse movement and mouse button presses, optionally coordinated with single or multiple keyboard presses or holds; contact movements such as taps, drags, scrolls, etc., on touch-pads; pen stylus inputs; movement of the device; oral instructions; detected eye movements; biometric inputs; and/or any combination thereof are optionally utilized as inputs corresponding to sub-events which define an event to be recognized.

FIG. 2 illustrates a portable multifunction device 100 having a touch screen (e.g., touch-sensitive display system 112, FIG. 1A) in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface (UI) 200. In this embodiment, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers 202 (not drawn to scale in the figure) or one or more styluses 203 (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward) and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device 100. In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap.

Device 100 optionally also includes one or more physical buttons, such as “home” or menu button 204. As described previously, menu button 204 is, optionally, used to navigate to any application 136 in a set of applications that are, optionally executed on device 100. Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on the touch-screen display.

In some embodiments, device 100 includes the touch-screen display, menu button 204, push button 206 for powering the device on/off and locking the device, volume adjustment button(s) 208, Subscriber Identity Module (SIM) card slot 210, head set jack 212, and docking/charging external port 124. Push button 206 is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In some embodiments, device 100 also accepts verbal input for activation or deactivation of some functions through microphone 113. Device 100 also, optionally, includes one or more contact intensity sensors 165 for detecting intensity of contacts on touch-sensitive display system 112 and/or one or more tactile output generators 163 for generating tactile outputs for a user of device 100.

FIG. 3 is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device 300 need not be portable. In some embodiments, device 300 is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child's learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device 300 typically includes one or more processing units (CPU's) 310, one or more network or other communications interfaces 360, memory 370, and one or more communication buses 320 for interconnecting these components. Communication buses 320 optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device 300 includes input/output (I/O) interface 330 comprising display 340, which is typically a touch-screen display. I/O interface 330 also optionally includes a keyboard and/or mouse (or other pointing device) 350 and touchpad 355, tactile output generator 357 for generating tactile outputs on device 300 (e.g., similar to tactile output generator(s) 163 described above with reference to FIG. 1A), sensors 359 (e.g., touch-sensitive, optical, contact intensity, proximity, acceleration, attitude, and/or magnetic sensors similar to sensors 112, 164, 165, 166, 167, 168, and 169 described above with reference to FIG. 1A). Memory 370 includes high-speed random access memory, such as DRAM, SRAM, DDR RAM or other random access solid state memory devices; and optionally includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory 370 optionally includes one or more storage devices remotely located from CPU(s) 310. In some embodiments, memory 370 stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory 102 of portable multifunction device 100 (FIG. 1A), or a subset thereof. Furthermore, memory 370 optionally stores additional programs, modules, and data structures not present in memory 102 of portable multifunction device 100. For example, memory 370 of device 300 optionally stores drawing module 380, presentation module 382, word processing module 384, website creation module 386, disk authoring module 388, and/or spreadsheet module 390, while memory 102 of portable multifunction device 100 (FIG. 1A) optionally does not store these modules.

Each of the above identified elements in FIG. 3 are, optionally, stored in one or more of the previously mentioned memory devices. Each of the above identified modules corresponds to a set of instructions for performing a function described above. The above identified modules or programs (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules are, optionally, combined or otherwise re-arranged in various embodiments. In some embodiments, memory 370 optionally stores a subset of the modules and data structures identified above. Furthermore, memory 370 optionally stores additional modules and data structures not described above.

FIG. 4 is a block diagram of an exemplary electronic stylus 203 in accordance with some embodiments. Electronic stylus 203 is sometimes simply called a stylus. Stylus 203 includes memory 402 (which optionally includes one or more computer readable storage mediums), memory controller 422, one or more processing units (CPUs) 420, peripherals interface 418, RF circuitry 408, input/output (I/O) subsystem 406, and other input or control devices 416. Stylus 203 optionally includes external port 424 and one or more optical sensors 464. Stylus 203 optionally includes one or more intensity sensors 465 for detecting intensity of contacts of stylus 203 on device 100 (e.g., when stylus 203 is used with a touch-sensitive surface such as touch-sensitive display system 112 of device 100) or on other surfaces (e.g., a desk surface). Stylus 203 optionally includes one or more tactile output generators 463 for generating tactile outputs on stylus 203. These components optionally communicate over one or more communication buses or signal lines 403.

In some embodiments, the term “tactile output,” discussed above, refers to physical displacement of an accessory (e.g., stylus 203) of a device (e.g., device 100) relative to a previous position of the accessory, physical displacement of a component of an accessory relative to another component of the accessory, or displacement of the component relative to a center of mass of the accessory that will be detected by a user with the user's sense of touch. For example, in situations where the accessory or the component of the accessory is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user's hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the accessory or the component of the accessory. For example, movement of a component (e.g., the housing of stylus 203) is, optionally, interpreted by the user as a “click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as a “click” even when there is no movement of a physical actuator button associated with the stylus that is physically pressed (e.g., displaced) by the user's movements. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., a “click,”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user.

It should be appreciated that stylus 203 is only one example of an electronic stylus, and that stylus 203 optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in FIG. 4 are implemented in hardware, software, firmware, or a combination thereof, including one or more signal processing and/or application specific integrated circuits.

Memory 402 optionally includes high-speed random access memory and optionally also includes non-volatile memory, such as one or more flash memory devices, or other non-volatile solid-state memory devices. Access to memory 402 by other components of stylus 203, such as CPU(s) 420 and the peripherals interface 418, is, optionally, controlled by memory controller 422.

Peripherals interface 418 can be used to couple input and output peripherals of the stylus to CPU(s) 420 and memory 402. The one or more processors 420 run or execute various software programs and/or sets of instructions stored in memory 402 to perform various functions for stylus 203 and to process data.

In some embodiments, peripherals interface 418, CPU(s) 420, and memory controller 422 are, optionally, implemented on a single chip, such as chip 404. In some other embodiments, they are, optionally, implemented on separate chips.

RF (radio frequency) circuitry 408 receives and sends RF signals, also called electromagnetic signals. RF circuitry 408 converts electrical signals to/from electromagnetic signals and communicates with device 100 or 300, communications networks, and/or other communications devices via the electromagnetic signals. RF circuitry 408 optionally includes well-known circuitry for performing these functions, including but not limited to an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, a subscriber identity module (SIM) card, memory, and so forth. RF circuitry 408 optionally communicates with networks, such as the Internet, also referred to as the World Wide Web (WWW), an intranet and/or a wireless network, such as a cellular telephone network, a wireless local area network (LAN) and/or a metropolitan area network (MAN), and other devices by wireless communication. The wireless communication optionally uses any of a plurality of communications standards, protocols and technologies, including but not limited to Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), high-speed downlink packet access (HSDPA), high-speed uplink packet access (HSUPA), Evolution, Data-Only (EV-DO), HSPA, HSPA+, Dual-Cell HSPA (DC-HSPDA), long term evolution (LTE), near field communication (NFC), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11ac, IEEE 802.11ax, IEEE 802.11b, IEEE 802.11g and/or IEEE 802.11n), voice over Internet Protocol (VoIP), Wi-MAX, a protocol for e-mail (e.g., Internet message access protocol (IMAP) and/or post office protocol (POP)), instant messaging (e.g., extensible messaging and presence protocol (XMPP), Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE), Instant Messaging and Presence Service (IMPS)), and/or Short Message Service (SMS), or any other suitable communication protocol, including communication protocols not yet developed as of the filing date of this document.

I/O subsystem 406 couples input/output peripherals on stylus 203, such as other input or control devices 416, with peripherals interface 418. I/O subsystem 406 optionally includes optical sensor controller 458, intensity sensor controller 459, haptic feedback controller 461, and one or more input controllers 460 for other input or control devices. The one or more input controllers 460 receive/send electrical signals from/to other input or control devices 416. The other input or control devices 416 optionally include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, click wheels, and so forth. In some alternate embodiments, input controller(s) 460 are, optionally, coupled with any (or none) of the following: an infrared port and/or a USB port.

Stylus 203 also includes power system 462 for powering the various components. Power system 462 optionally includes a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices and/or portable accessories.

Stylus 203 optionally also includes one or more optical sensors 464. FIG. 4 shows an optical sensor coupled with optical sensor controller 458 in I/O subsystem 406. Optical sensor(s) 464 optionally include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor(s) 464 receive light from the environment, projected through one or more lens, and converts the light to data representing an image.

Stylus 203 optionally also includes one or more contact intensity sensors 465. FIG. 4 shows a contact intensity sensor coupled with intensity sensor controller 459 in I/O subsystem 406. Contact intensity sensor(s) 465 optionally include one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a surface). Contact intensity sensor(s) 465 receive contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a tip of stylus 203.

Stylus 203 optionally also includes one or more proximity sensors 466. FIG. 4 shows proximity sensor 466 coupled with peripherals interface 418. Alternately, proximity sensor 466 is coupled with input controller 460 in I/O subsystem 406. In some embodiments, the proximity sensor determines proximity of stylus 203 to an electronic device (e.g., device 100).

Stylus 203 optionally also includes one or more tactile output generators 463. FIG. 4 shows a tactile output generator coupled with haptic feedback controller 461 in I/O subsystem 406. Tactile output generator(s) 463 optionally include one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Tactile output generator(s) 463 receive tactile feedback generation instructions from haptic feedback module 433 and generates tactile outputs on stylus 203 that are capable of being sensed by a user of stylus 203. In some embodiments, at least one tactile output generator is collocated with, or proximate to, a length (e.g., a body or a housing) of stylus 203 and, optionally, generates a tactile output by moving stylus 203 vertically (e.g., in a direction parallel to the length of stylus 203) or laterally (e.g., in a direction normal to the length of stylus 203).

Stylus 203 optionally also includes one or more accelerometers 467, gyroscopes 468, and/or magnetometers 469 (e.g., as part of an inertial measurement unit (IMU)) for obtaining information concerning the location and positional state of stylus 203. FIG. 4 shows sensors 467, 468, and 469 coupled with peripherals interface 418. Alternately, sensors 467, 468, and 469 are, optionally, coupled with an input controller 460 in I/O subsystem 406. Stylus 203 optionally includes a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location of stylus 203.

In some embodiments, the software components stored in memory 402 include operating system 426, communication module (or set of instructions) 428, contact/motion module (or set of instructions) 430, position module (or set of instructions) 431, and Global Positioning System (GPS) module (or set of instructions) 435. Furthermore, in some embodiments, memory 402 stores device/global internal state 457, as shown in FIG. 4. Device/global internal state 457 includes one or more of: sensor state, including information obtained from the stylus's various sensors and other input or control devices 416; positional state, including information regarding the stylus's position (e.g., position, orientation, tilt, roll and/or distance, as shown in FIGS. 5A and 5B) relative to a device (e.g., device 100); and location information concerning the stylus's location (e.g., determined by GPS module 435).

Operating system 426 (e.g., iOS, Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, power management, etc.) and facilitates communication between various hardware and software components.

Communication module 428 optionally facilitates communication with other devices over one or more external ports 424 and also includes various software components for handling data received by RF circuitry 408 and/or external port 424. External port 424 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a Lightning connector that is the same as, or similar to and/or compatible with the Lightning connector used in some iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif.

Contact/motion module 430 optionally detects contact with stylus 203 and other touch-sensitive devices of stylus 203 (e.g., buttons or other touch-sensitive components of stylus 203). Contact/motion module 430 includes software components for performing various operations related to detection of contact (e.g., detection of a tip of the stylus with a touch-sensitive display, such as touch screen 112 of device 100, or with another surface, such as a desk surface), such as determining if contact has occurred (e.g., detecting a touch-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement (e.g., across touch screen 112 of device 100), and determining if the contact has ceased (e.g., detecting a lift-off event or a break in contact). In some embodiments, contact/motion module 430 receives contact data from I/O subsystem 406. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. As noted above, in some embodiments, one or more of these operations related to detection of contact are performed by the device using contact/motion module 130 (in addition to or in place of the stylus using contact/motion module 430).

Contact/motion module 430 optionally detects a gesture input by stylus 203. Different gestures with stylus 203 have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a single tap gesture includes detecting a touch-down event followed by detecting a lift-off event at the same position (or substantially the same position) as the touch-down event (e.g., at the position of an icon). As another example, detecting a swipe gesture includes detecting a touch-down event followed by detecting one or more stylus-dragging events, and subsequently followed by detecting a lift-off event. As noted above, in some embodiments, gesture detection is performed by the device using contact/motion module 130 (in addition to or in place of the stylus using contact/motion module 430).

Position module 431, in conjunction with accelerometers 467, gyroscopes 468, and/or magnetometers 469, optionally detects positional information concerning the stylus, such as the stylus's attitude (roll, pitch, and/or yaw) in a particular frame of reference. Position module 431, in conjunction with accelerometers 467, gyroscopes 468, and/or magnetometers 469, optionally detects stylus movement gestures, such as flicks, taps, and rolls of the stylus. Position module 431 includes software components for performing various operations related to detecting the position of the stylus and detecting changes to the position of the stylus in a particular frame of reference. In some embodiments, position module 431 detects the positional state of the stylus relative to the device and detects changes to the positional state of the stylus relative to the device. As noted above, in some embodiments, device 100 or 300 determines the positional state of the stylus relative to the device and changes to the positional state of the stylus using position module 131 (in addition to or in place of the stylus using position module 431).

Haptic feedback module 433 includes various software components for generating instructions used by tactile output generator(s) 463 to produce tactile outputs at one or more locations on stylus 203 in response to user interactions with stylus 203.

GPS module 435 determines the location of the stylus and provides this information for use in various applications (e.g., to applications that provide location-based services such as an application to find missing devices and/or accessories).

Each of the above identified modules and applications correspond to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules are, optionally, combined or otherwise re-arranged in various embodiments. In some embodiments, memory 402 optionally stores a subset of the modules and data structures identified above. Furthermore, memory 402 optionally stores additional modules and data structures not described above.

FIGS. 5A-5B illustrate a positional state of stylus 203 relative to a touch-sensitive surface (e.g., touch screen 112 of device 100) in accordance with some embodiments. In some embodiments, the positional state of stylus 203 corresponds to (or indicates): a position of a projection of a tip (or other representative portion) of the stylus on the touch-sensitive surface (e.g., (x,y) position 504, FIG. 5A), an orientation of the stylus relative to the touch-sensitive surface (e.g., orientation 506, FIG. 5A), a tilt of the stylus relative to the touch-sensitive surface (e.g., tilt 512, FIG. 5B), and/or a distance of the stylus relative to the touch-sensitive surface (e.g., distance 514, FIG. 5B). In some embodiments, the positional state of stylus 203 corresponds to (or indicates) a pitch, yaw, and/or roll of the stylus (e.g., an attitude of the stylus relative to a particular frame of reference, such as a touch-sensitive surface (e.g., touch screen 112) or the ground). In some embodiments, the positional state includes a set of positional parameters (e.g., one or more positional parameters). In some embodiments, the positional state is detected in accordance with one or more measurements from stylus 203 that are sent to an electronic device (e.g., device 100). For example, the stylus measures the tilt (e.g., tilt 512, FIG. 5B) and/or the orientation (e.g., orientation 506, FIG. 5A) of the stylus and sends the measurement to device 100. In some embodiments, the positional state is detected in accordance with raw output, from one or more electrodes in the stylus, that is sensed by a touch-sensitive surface (e.g., touch screen 112 of device 100) instead of, or in combination with positional state detected in accordance with one or more measurements from stylus 203. For example, the touch-sensitive surface receives raw output from one or more electrodes in the stylus and calculates the tilt and/or the orientation of the stylus based on the raw output (optionally, in conjunction with positional state information provided by the stylus based on sensor measurements generated by the stylus).

FIG. 5A illustrates stylus 203 relative to a touch-sensitive surface (e.g., touch screen 112 of device 100) from a viewpoint directly above the touch-sensitive surface, in accordance with some embodiments. In FIG. 5A, z axis 594 points out of the page (i.e., in a direction normal to a plane of touch screen 112), x axis 590 is parallel to a first edge (e.g., a length) of touch screen 112, y axis 592 is parallel to a second edge (e.g., a width) of touch screen 112, and y axis 592 is perpendicular to x axis 590.

FIG. 5A illustrates the tip of stylus 203 at (x,y) position 504. In some embodiments, the tip of stylus 203 is a terminus of the stylus configured for determining proximity of the stylus to a touch-sensitive surface (e.g., touch screen 112). In some embodiments, the projection of the tip of the stylus on the touch-sensitive surface is an orthogonal projection. In other words, the projection of the tip of the stylus on the touch-sensitive surface is a point at the end of a line from the stylus tip to the touch-sensitive surface that is normal to a surface of the touch-sensitive surface (e.g., (x,y) position 504 at which the tip of the stylus would touch the touch-sensitive surface if the stylus were moved directly along a path normal to the touch-sensitive surface). In some embodiments, the (x,y) position at the lower left corner of touch screen 112 is position (0,0) (e.g., (0,0) position 502) and other (x,y) positions on touch screen 112 are relative to the lower left corner of touch screen 112. Alternatively, in some embodiments, the (0,0) position is located at another position of touch screen 112 (e.g., in the center of touch screen 112) and other (x,y) positions are relative to the (0,0) position of touch screen 112.

Further, FIG. 5A illustrates stylus 203 with orientation 506. In some embodiments, orientation 506 is an orientation of a projection of stylus 203 onto touch screen 112 (e.g., an orthogonal projection of a length of stylus 203 or a line corresponding to the line between the projection of two different points of stylus 203 onto touch screen 112). In some embodiments, orientation 506 is relative to at least one axis in a plane parallel to touch screen 112. In some embodiments, orientation 506 is relative to a single axis in a plane parallel to touch screen 112 (e.g., axis 508, with a clockwise rotation angle from axis 508 ranging from 0 degrees to 360 degrees, as shown in FIG. 5A). Alternatively, in some embodiments, orientation 506 is relative to a pair of axes in a plane parallel to touch screen 112 (e.g., x axis 590 and y axis 592, as shown in FIG. 5A, or a pair of axes associated with an application displayed on touch screen 112).

In some embodiments, an indication (e.g., indication 516) is displayed on a touch-sensitive display (e.g., touch screen 112 of device 100). In some embodiments, indication 516 shows where the stylus will touch (or mark) the touch-sensitive display before the stylus touches the touch-sensitive display. In some embodiments, indication 516 is a portion of a mark that is being drawn on the touch-sensitive display. In some embodiments, indication 516 is separate from a mark that is being drawn on the touch-sensitive display and corresponds to a virtual “pen tip” or other element that indicates where a mark will be drawn on the touch-sensitive display.

In some embodiments, indication 516 is displayed in accordance with the positional state of stylus 203. For example, in some circumstances, indication 516 is displaced from (x,y) position 504 (as shown in FIGS. 5A and 5B), and in other circumstances, indication 516 is not displaced from (x,y) position 504 (e.g., indication 516 is displayed at or near (x,y) position 504 when tilt 512 is zero degrees). In some embodiments, indication 516 is displayed, in accordance with the positional state of the stylus, with varying color, size (or radius or area), opacity, and/or other characteristics. In some embodiments, the displayed indication accounts for thickness of a glass layer on the touch-sensitive display, so as to carry through the indication “onto the pixels” of the touch-sensitive display, rather than displaying the indication “on the glass” that covers the pixels.

FIG. 5B illustrates stylus 203 relative to a touch-sensitive surface (e.g., touch screen 112 of device 100) from a side viewpoint of the touch-sensitive surface, in accordance with some embodiments. In FIG. 5B, z axis 594 points in a direction normal to the plane of touch screen 112, x axis 590 is parallel to a first edge (e.g., a length) of touch screen 112, y axis 592 is parallel to a second edge (e.g., a width) of touch screen 112, and y axis 592 is perpendicular to x axis 590.

FIG. 5B illustrates stylus 203 with tilt 512. In some embodiments, tilt 512 is an angle relative to a normal (e.g., normal 510) to a surface of the touch-sensitive surface (also called simply the normal to the touch-sensitive surface). As shown in FIG. 5B, tilt 512 is zero when the stylus is perpendicular/normal to the touch-sensitive surface (e.g., when stylus 203 is parallel to normal 510) and the tilt increases as the stylus is tilted closer to being parallel to the touch-sensitive surface.

Further, FIG. 5B illustrates distance 514 of stylus 203 relative to the touch-sensitive surface. In some embodiments, distance 514 is the distance from the tip of stylus 203 to the touch-sensitive surface, in a direction normal to the touch-sensitive surface. For example, in FIG. 5B, distance 514 is the distance from the tip of stylus 203 to (x,y) position 504.

Although the terms, “x axis,” “y axis,” and “z axis,” are used herein to illustrate certain directions in particular figures, it will be understood that these terms do not refer to absolute directions. In other words, an “x axis” could be any respective axis, and a “y axis” could be a particular axis that is distinct from the x axis. Typically, the x axis is perpendicular to the y axis. Similarly, a “z axis” is distinct from the “x axis” and the “y axis,” and is typically perpendicular to both the “x axis” and the “y axis.”

Further, FIG. 5B illustrates roll 518, a rotation about the length (long axis) of stylus 203.

Attention is now directed towards embodiments of user interfaces (“UI”) that are, optionally, implemented on portable multifunction device 100.

FIG. 6A illustrates an exemplary user interface for a menu of applications on portable multifunction device 100 in accordance with some embodiments. Similar user interfaces are, optionally, implemented on device 300. In some embodiments, user interface 600 includes the following elements, or a subset or superset thereof:

-   -   Signal strength indicator(s) 602 for wireless communication(s),         such as cellular and Wi-Fi signals;     -   Time 604;     -   Bluetooth indicator 605;     -   Battery status indicator 606;     -   Tray 608 with icons for frequently used applications, such as:         -   Icon 616 for telephone module 138, labeled “Phone,” which             optionally includes an indicator 614 of the number of missed             calls or voicemail messages;         -   Icon 618 for e-mail client module 140, labeled “Mail,” which             optionally includes an indicator 610 of the number of unread             e-mails;         -   Icon 620 for browser module 147, labeled “Browser;” and         -   Icon 622 for video and music player module 152, also             referred to as iPod® (trademark of Apple Inc.) module 152,             labeled “iPod;” and     -   Icons for other applications, such as:         -   Icon 624 for IM module 141, labeled “Messages;”         -   Icon 626 for calendar module 148, labeled “Calendar;”         -   Icon 628 for image management module 144, labeled “Photos;”         -   Icon 630 for camera module 143, labeled “Camera;”         -   Icon 632 for video editing module 155, labeled “Video             Editing;”         -   Icon 634 for stocks widget 149-2, labeled “Stocks;”         -   Icon 636 for map module 154, labeled “Map;”         -   Icon 638 for weather widget 149-1, labeled “Weather;”         -   Icon 640 for alarm clock widget 149-4, labeled “Clock;”         -   Icon 642 for workout support module 142, labeled “Workout             Support;”         -   Icon 644 for notes module 153, labeled “Notes;” and         -   Icon 646 for a settings application or module, which             provides access to settings for device 100 and its various             applications 136.

It should be noted that the icon labels illustrated in FIG. 6A are merely exemplary. For example, in some embodiments, icon 622 for video and music player module 152 is labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon.

FIG. 6B illustrates an exemplary user interface on a device (e.g., device 300, FIG. 3) with a touch-sensitive surface 651 (e.g., a tablet or touchpad 355, FIG. 3) that is separate from the display 650. Device 300 also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors 359) for detecting intensity of contacts on touch-sensitive surface 651 and/or one or more tactile output generators 357 for generating tactile outputs for a user of device 300.

FIG. 6B illustrates an exemplary user interface on a device (e.g., device 300, FIG. 3) with a touch-sensitive surface 651 (e.g., a tablet or touchpad 355, FIG. 3) that is separate from the display 650. Although many of the examples that follow will be given with reference to inputs on touch screen display 112 (where the touch sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in FIG. 6B. In some embodiments, the touch-sensitive surface (e.g., 651 in FIG. 6B) has a primary axis (e.g., 652 in FIG. 6B) that corresponds to a primary axis (e.g., 653 in FIG. 6B) on the display (e.g., 650). In accordance with these embodiments, the device detects contacts (e.g., 660 and 662 in FIG. 6B) with the touch-sensitive surface 651 at locations that correspond to respective locations on the display (e.g., in FIG. 6B, 660 corresponds to 668 and 662 corresponds to 670). In this way, user inputs (e.g., contacts 660 and 662, and movements thereof) detected by the device on the touch-sensitive surface (e.g., 651 in FIG. 6B) are used by the device to manipulate the user interface on the display (e.g., 650 in FIG. 6B) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein.

Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures, etc.), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse based input or a stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously.

As used herein, the term “focus selector” refers to an input element that indicates a current part of a user interface with which a user is interacting. In some implementations that include a cursor or other location marker, the cursor acts as a “focus selector,” so that when an input (e.g., a press input) is detected on a touch-sensitive surface (e.g., touchpad 355 in FIG. 3 or touch-sensitive surface 651 in FIG. 6B) while the cursor is over a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations that include a touch-screen display (e.g., touch-sensitive display system 112 in FIG. 1A or the touch screen in FIG. 6A) that enables direct interaction with user interface elements on the touch-screen display, a detected contact on the touch-screen acts as a “focus selector,” so that when an input (e.g., a press input by the contact) is detected on the touch-screen display at a location of a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations, focus is moved from one region of a user interface to another region of the user interface without corresponding movement of a cursor or movement of a contact on a touch-screen display (e.g., by using a tab key or arrow keys to move focus from one button to another button); in these implementations, the focus selector moves in accordance with movement of focus between different regions of the user interface. Without regard to the specific form taken by the focus selector, the focus selector is generally the user interface element (or contact on a touch-screen display) that is controlled by the user so as to communicate the user's intended interaction with the user interface (e.g., by indicating, to the device, the element of the user interface with which the user is intending to interact). For example, the location of a focus selector (e.g., a cursor, a contact, or a selection box) over a respective button while a press input is detected on the touch-sensitive surface (e.g., a touchpad or touch screen) will indicate that the user is intending to activate the respective button (as opposed to other user interface elements shown on a display of the device).

As used in the specification and claims, the term “intensity” of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact or a stylus contact) on the touch-sensitive surface, or to a substitute (proxy) for the force or pressure of a contact on the touch-sensitive surface. The intensity of a contact has a range of values that includes at least four distinct values and more typically includes hundreds of distinct values (e.g., at least 256). Intensity of a contact is, optionally, determined (or measured) using various approaches and various sensors or combinations of sensors. For example, one or more force sensors underneath or adjacent to the touch-sensitive surface are, optionally, used to measure force at various points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., a weighted average or a sum) to determine an estimated force of a contact. Similarly, a pressure-sensitive tip of a stylus is, optionally, used to determine a pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and/or changes thereto, the capacitance of the touch-sensitive surface proximate to the contact and/or changes thereto, and/or the resistance of the touch-sensitive surface proximate to the contact and/or changes thereto are, optionally, used as a substitute for the force or pressure of the contact on the touch-sensitive surface. In some implementations, the substitute measurements for contact force or pressure are used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the substitute measurements). In some implementations, the substitute measurements for contact force or pressure are converted to an estimated force or pressure and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure). Using the intensity of a contact as an attribute of a user input allows for user access to additional device functionality that may otherwise not be readily accessible by the user on a reduced-size device with limited real estate for displaying affordances (e.g., on a touch-sensitive display) and/or receiving user input (e.g., via a touch-sensitive display, a touch-sensitive surface, or a physical/mechanical control such as a knob or a button).

In some embodiments, contact/motion module 130 and/or 430 uses a set of one or more intensity thresholds to determine whether an operation has been performed by a user (e.g., to determine whether a user has “clicked” on an icon). In some embodiments, at least a subset of the intensity thresholds are determined in accordance with software parameters (e.g., the intensity thresholds are not determined by the activation thresholds of particular physical actuators and can be adjusted without changing the physical hardware of device 100). For example, a mouse “click” threshold of a trackpad or touch-screen display can be set to any of a large range of predefined thresholds values without changing the trackpad or touch-screen display hardware. Additionally, in some embodiments, a user of the device is provided with software settings for adjusting one or more of the set of intensity thresholds (e.g., by adjusting individual intensity thresholds and/or by adjusting a plurality of intensity thresholds at once with a system-level click “intensity” parameter).

As used in the specification and claims, the term “characteristic intensity” of a contact refers to a characteristic of the contact based on one or more intensities of the contact. In some embodiments, the characteristic intensity is based on multiple intensity samples. The characteristic intensity is, optionally, based on a predefined number of intensity samples, or a set of intensity samples collected during a predetermined time period (e.g., 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10 seconds) relative to a predefined event (e.g., after detecting the contact, prior to detecting liftoff of the contact, before or after detecting a start of movement of the contact, prior to detecting an end of the contact, before or after detecting an increase in intensity of the contact, and/or before or after detecting a decrease in intensity of the contact). A characteristic intensity of a contact is, optionally based on one or more of: a maximum value of the intensities of the contact, a mean value of the intensities of the contact, an average value of the intensities of the contact, a top 10 percentile value of the intensities of the contact, a value at the half maximum of the intensities of the contact, a value at the 90 percent maximum of the intensities of the contact, or the like. In some embodiments, the duration of the contact is used in determining the characteristic intensity (e.g., when the characteristic intensity is an average of the intensity of the contact over time). In some embodiments, the characteristic intensity is compared to a set of one or more intensity thresholds to determine whether an operation has been performed by a user. For example, the set of one or more intensity thresholds may include a first intensity threshold and a second intensity threshold. In this example, a contact with a characteristic intensity that does not exceed the first threshold results in a first operation, a contact with a characteristic intensity that exceeds the first intensity threshold and does not exceed the second intensity threshold results in a second operation, and a contact with a characteristic intensity that exceeds the second intensity threshold results in a third operation. In some embodiments, a comparison between the characteristic intensity and one or more intensity thresholds is used to determine whether or not to perform one or more operations (e.g., whether to perform a respective option or forgo performing the respective operation) rather than being used to determine whether to perform a first operation or a second operation.

In some embodiments, a portion of a gesture is identified for purposes of determining a characteristic intensity. For example, a touch-sensitive surface may receive a continuous swipe contact transitioning from a start location and reaching an end location (e.g., a drag gesture), at which point the intensity of the contact increases. In this example, the characteristic intensity of the contact at the end location may be based on only a portion of the continuous swipe contact, and not the entire swipe contact (e.g., only the portion of the swipe contact at the end location). In some embodiments, a smoothing algorithm may be applied to the intensities of the swipe contact prior to determining the characteristic intensity of the contact. For example, the smoothing algorithm optionally includes one or more of: an unweighted sliding-average smoothing algorithm, a triangular smoothing algorithm, a median filter smoothing algorithm, and/or an exponential smoothing algorithm. In some circumstances, these smoothing algorithms eliminate narrow spikes or dips in the intensities of the swipe contact for purposes of determining a characteristic intensity.

The user interface figures described herein optionally include various intensity diagrams that show the current intensity of the contact on the touch-sensitive surface relative to one or more intensity thresholds (e.g., a contact detection intensity threshold IT₀, a light press intensity threshold IT_(L), a deep press intensity threshold IT_(D) (e.g., that is at least initially higher than I_(L)), and/or one or more other intensity thresholds (e.g., an intensity threshold I_(H) that is lower than I_(L))). This intensity diagram is typically not part of the displayed user interface, but is provided to aid in the interpretation of the figures. In some embodiments, the light press intensity threshold corresponds to an intensity at which the device will perform operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, the deep press intensity threshold corresponds to an intensity at which the device will perform operations that are different from operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, when a contact is detected with a characteristic intensity below the light press intensity threshold (e.g., and above a nominal contact-detection intensity threshold IT₀ below which the contact is no longer detected), the device will move a focus selector in accordance with movement of the contact on the touch-sensitive surface without performing an operation associated with the light press intensity threshold or the deep press intensity threshold. Generally, unless otherwise stated, these intensity thresholds are consistent between different sets of user interface figures.

In some embodiments, the response of the device to inputs detected by the device depends on criteria based on the contact intensity during the input. For example, for some “light press” inputs, the intensity of a contact exceeding a first intensity threshold during the input triggers a first response. In some embodiments, the response of the device to inputs detected by the device depends on criteria that include both the contact intensity during the input and time-based criteria. For example, for some “deep press” inputs, the intensity of a contact exceeding a second intensity threshold during the input, greater than the first intensity threshold for a light press, triggers a second response only if a delay time has elapsed between meeting the first intensity threshold and meeting the second intensity threshold. This delay time is typically less than 200 ms in duration (e.g., 40, 100, or 120 ms, depending on the magnitude of the second intensity threshold, with the delay time increasing as the second intensity threshold increases). This delay time helps to avoid accidental deep press inputs. As another example, for some “deep press” inputs, there is a reduced-sensitivity time period that occurs after the time at which the first intensity threshold is met. During the reduced-sensitivity time period, the second intensity threshold is increased. This temporary increase in the second intensity threshold also helps to avoid accidental deep press inputs. For other deep press inputs, the response to detection of a deep press input does not depend on time-based criteria.

In some embodiments, one or more of the input intensity thresholds and/or the corresponding outputs vary based on one or more factors, such as user settings, contact motion, input timing, application running, rate at which the intensity is applied, number of concurrent inputs, user history, environmental factors (e.g., ambient noise), focus selector position, and the like. Exemplary factors are described in U.S. patent application Ser. Nos. 14/399,606 and 14/624,296, which are incorporated by reference herein in their entireties.

An increase of characteristic intensity of the contact from an intensity below the light press intensity threshold IT_(L) to an intensity between the light press intensity threshold IT_(L) and the deep press intensity threshold IT_(D) is sometimes referred to as a “light press” input. An increase of characteristic intensity of the contact from an intensity below the deep press intensity threshold IT_(D) to an intensity above the deep press intensity threshold IT_(D) is sometimes referred to as a “deep press” input. An increase of characteristic intensity of the contact from an intensity below the contact-detection intensity threshold IT₀ to an intensity between the contact-detection intensity threshold IT₀ and the light press intensity threshold IT_(L) is sometimes referred to as detecting the contact on the touch-surface. A decrease of characteristic intensity of the contact from an intensity above the contact-detection intensity threshold IT₀ to an intensity below the contact-detection intensity threshold IT₀ is sometimes referred to as detecting liftoff of the contact from the touch-surface. In some embodiments IT₀ is zero. In some embodiments, IT₀ is greater than zero. In some illustrations a shaded circle or oval is used to represent intensity of a contact on the touch-sensitive surface. In some illustrations, a circle or oval without shading is used represent a respective contact on the touch-sensitive surface without specifying the intensity of the respective contact.

In some embodiments, described herein, one or more operations are performed in response to detecting a gesture that includes a respective press input or in response to detecting the respective press input performed with a respective contact (or a plurality of contacts), where the respective press input is detected based at least in part on detecting an increase in intensity of the contact (or plurality of contacts) above a press-input intensity threshold. In some embodiments, the respective operation is performed in response to detecting the increase in intensity of the respective contact above the press-input intensity threshold (e.g., the respective operation is performed on a “down stroke” of the respective press input). In some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the press-input threshold (e.g., the respective operation is performed on an “up stroke” of the respective press input).

In some embodiments, the device employs intensity hysteresis to avoid accidental inputs sometimes termed “jitter,” where the device defines or selects a hysteresis intensity threshold with a predefined relationship to the press-input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press-input intensity threshold or the hysteresis intensity threshold is 75%, 90%, or some reasonable proportion of the press-input intensity threshold). Thus, in some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the hysteresis intensity threshold that corresponds to the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the hysteresis intensity threshold (e.g., the respective operation is performed on an “up stroke” of the respective press input). Similarly, in some embodiments, the press input is detected only when the device detects an increase in intensity of the contact from an intensity at or below the hysteresis intensity threshold to an intensity at or above the press-input intensity threshold and, optionally, a subsequent decrease in intensity of the contact to an intensity at or below the hysteresis intensity, and the respective operation is performed in response to detecting the press input (e.g., the increase in intensity of the contact or the decrease in intensity of the contact, depending on the circumstances).

For ease of explanation, the description of operations performed in response to a press input associated with a press-input intensity threshold or in response to a gesture including the press input are, optionally, triggered in response to detecting: an increase in intensity of a contact above the press-input intensity threshold, an increase in intensity of a contact from an intensity below the hysteresis intensity threshold to an intensity above the press-input intensity threshold, a decrease in intensity of the contact below the press-input intensity threshold, or a decrease in intensity of the contact below the hysteresis intensity threshold corresponding to the press-input intensity threshold. Additionally, in examples where an operation is described as being performed in response to detecting a decrease in intensity of a contact below the press-input intensity threshold, the operation is, optionally, performed in response to detecting a decrease in intensity of the contact below a hysteresis intensity threshold corresponding to, and lower than, the press-input intensity threshold. As described above, in some embodiment, the triggering of these responses also depends on time-based criteria being met (e.g., a delay time has elapsed between a first intensity threshold being met and a second intensity threshold being met).

User Interfaces and Associated Processes

Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that may be implemented on an electronic device, such as portable multifunction device 100 or device 300, with a touch-sensitive display and optionally one or more sensors to detect signals from a stylus associated with the device.

FIGS. 7A-7R illustrate exemplary user interfaces for viewing and editing documents with stylus and finger inputs in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in FIGS. 8A-8D. Although some of the examples which follow will be given with reference to inputs on a touch-screen display (where the touch-sensitive surface and the display are combined, for example on touch screen 112), in some embodiments, the device detects inputs on a touch-sensitive surface 651 that is separate from the display 650, as shown in FIG. 6B. For sake of clarity, FIGS. 7A-7R simply show touch screen 112 of device 100, without showing other details of device 100.

In some embodiments, the device is an electronic device with a separate display (e.g., display 650) and a separate touch-sensitive surface (e.g., touch-sensitive surface 651). In some embodiments, the device is portable multifunction device 100, the display is touch-sensitive display system 112, and the touch-sensitive surface includes tactile output generators 163 on the display (FIG. 1A). For convenience of explanation, the embodiments described with reference to FIGS. 7A-7R and 8A-8D will be discussed with reference to operations performed on a device with a touch-sensitive display system 112. In such embodiments, the focus selector is, optionally: a respective finger or stylus contact, a representative point corresponding to a finger or stylus contact (e.g., a centroid of a respective contact or a point associated with a respective contact), or a centroid of two or more contacts detected on the touch-sensitive display system 112. However, analogous operations are, optionally, performed on a device with a display 650 and a separate touch-sensitive surface 651 in response to detecting the contacts described in FIGS. 7A-7R on (or near) the touch-sensitive surface 651 while displaying the user interfaces shown in FIGS. 7A-7R on the display 650.

FIG. 7A illustrates an example of displaying a user interface of an application that views and edits images and Portable Document Files (PDFs) (e.g., an application such as the Preview application from Apple Inc. of Cupertino, Calif.). User interface 710 is displayed on a display (e.g., touch screen 112) of a device (e.g., device 100) and is responsive to contacts (e.g., a stylus contact and/or a finger contact) on the display (e.g., touch screen 112). User interface 710 includes content region 712 and first control region 714. In some embodiments, first control region 714 includes controls for editing the content in content region 712. In some embodiments, first control region 714 includes controls for navigating through the content in content region 712. In some embodiments, first control region 714 includes menu affordance 714-a, deletion affordance 714-b, revert affordance 714-c, edit mode affordance 714-d, and sharing affordance 714-e. In some embodiments, when an input (e.g., a tap input) is detected on menu affordance 714-a, a menu is displayed for opening a document. In some embodiments, when an input (e.g., a tap input) is detected on deletion affordance 714-b, the document is deleted. In some embodiments when an input (e.g., a tap input) is detected on revert affordance 714-c, changes are undone in the document (e.g., the most recent change or all changes made since opening the document). In some embodiments, when an input (e.g., a tap input) is detected on edit mode affordance 714-d, a second control region (e.g., second control region 716, FIG. 7B) is displayed. In some embodiments, when an input (e.g., a tap input) is detected on sharing affordance 714-e, a menu is displayed with options for sharing the document. In FIG. 7A, user interface 710 is displayed in a viewing mode (e.g., a read-only mode or other mode that does not permit markup or editing of the content).

FIG. 7B illustrates an example of detecting an input by a stylus contact (e.g., contact 718 by stylus 203) on the touch-sensitive display (e.g., touch screen 112) in the content region (e.g., content region 712). In some embodiments, in response to detecting an input by a stylus contact (e.g., contact 718 by stylus 203) in content region 712, user interface 710 changes from a viewing mode (e.g., in FIG. 7A) to an editing mode (e.g., in FIG. 7B), where the editing mode is distinct from the viewing mode. In some embodiments, the editing mode, as shown in FIG. 7B, is configured to enable drawing on content region 712 by a stylus (e.g., stylus 203). In some embodiments, in response to detecting an input by a stylus (e.g., contact 718 by stylus 203) in content region 712, second control region 716, distinct from first control region 714, is displayed. In some embodiments, second control region 716 includes one or more tools, such as a drawing tool (e.g., draw affordance 716-a) to enable drawing on content region 712 (e.g., where both stylus contacts and non-stylus contacts are enabled to make marks in the content region), a zoom tool (e.g., zoom affordance 716-b) to change the magnification of a selected portion of the document, a text tool (e.g., text affordance 716-c) to type text in a text box, a signature tool (e.g., signature affordance 716-d) to insert a signature into a PDF document, a color tool (e.g., color affordance 716-e) to change the color of marks drawn in the content region, a line thickness tool (e.g., thickness affordance 716-f) to change the thickness of the marks drawn in the content region, and a font tool (e.g., font affordance 716-g) to change the font type, font size, and/or font alignment of text in the document. In some embodiments, second control region 716 appears to fade in through an animation of second control region 716 appearing on the touch-sensitive display (e.g., touch screen 112) beginning at a time of initial contact of stylus 203 in content region 712.

FIGS. 7C-7D illustrate an example of detecting an input that includes movement across the touch-sensitive display (e.g., touch screen 112) by a stylus contact (e.g., contact 718 by stylus 203) in the content region (e.g., content region 712) and displaying a mark (e.g., mark 719) drawn in accordance with movement of the contact in the input.

FIG. 7E illustrates an example of detecting an input by a non-stylus contact (e.g., contact 720 by finger 202) on the touch-sensitive display (e.g., touch screen 112) in the content region (e.g., content region 712). In some embodiments, in response to detecting an input by a non-stylus contact (e.g., contact 720 by finger 202) in content region 712, user interface remains in viewing mode (e.g., as shown in FIGS. 7A and 7E) and forgoes changing from viewing mode to an editing mode.

FIGS. 7F-7G illustrate an example of detecting an input that includes movement across the touch-sensitive display (e.g., touch screen 112) by a non-stylus contact (e.g., contact 720 by finger 202) in the content region (e.g., content region 712) and performing a navigation operation in the content region in accordance with movement of the contact in the input. In this example, contact 720 by finger 202 moves up in content region 712 (as shown in FIG. 7F) and content region 712 is scrolled up accordingly (as shown in FIG. 7G).

FIGS. 7A and 7H illustrate an example of detecting an input (e.g., a tap input) by a stylus contact (e.g., contact 722 by stylus 203) in the first control region (e.g., first control region 714) on an edit mode affordance (e.g., edit mode affordance 714-d) and displaying the second control region (e.g., second control region 716, FIG. 7H). In some embodiments, in response to detecting a tap input by a stylus contact (e.g., contact 722 by stylus 203) on edit mode affordance 714-d, user interface 710 changes from a viewing mode (e.g., in FIG. 7A) to an editing mode (e.g., in FIG. 7H), where the editing mode is distinct from the viewing mode. In some embodiments, the editing mode, as shown in FIG. 7H, is configured to enable drawing on content region 712 by a stylus (e.g., stylus 203).

FIGS. 7A and 7I illustrate an example of detecting an input (e.g., a tap input) by a non-stylus contact (e.g., contact 724 by finger 202) in the first control region (e.g., first control region 714) on an edit mode affordance (e.g., edit mode affordance 714-d) and displaying the second control region (e.g., second control region 716, FIG. 7I). In some embodiments, in response to detecting a tap input by a non-stylus contact (e.g., contact 724 by finger 202) on edit mode affordance 714-d, user interface 710 changes from a viewing mode (e.g., in FIG. 7A) to an editing mode (e.g., in FIG. 7I), where the editing mode is distinct from the viewing mode. In some embodiments, the editing mode, as shown in FIG. 7I, is configured to enable drawing on content region 712 by a stylus (e.g., stylus 203), but non-stylus contacts in content region 712 do not create marks unless a draw affordance (e.g., draw affordance 716-a) is selected, as discussed below with respect to FIGS. 7J-7K.

FIGS. 7J-7K illustrate an example of detecting an input that includes movement across the touch-sensitive display (e.g., touch screen 112) by a non-stylus contact (e.g., contact 726 by finger 202) in the content region (e.g., content region 712) when a drawing tool is not selected. In this example, since a drawing tool is not selected (e.g., draw affordance 716-a is not selected), non-stylus contacts in content region 712 do not create marks. In some embodiments, non-stylus contacts in content region 712 create marks when a drawing tool is selected, as discussed below with respect to FIGS. 7L-7M. In some embodiments, as shown in FIG. 7K, a navigation operation is performed in accordance with movement of the non-stylus contact (e.g., contact 726 by finger 202). In this example, contact 726 by finger 202 moves up in content region 712 (as shown in FIG. 7J) and content region 712 is scrolled up accordingly (as shown in FIG. 7K).

FIGS. 7L-7M illustrate an example of detecting an input that includes movement across the touch-sensitive display (e.g., touch screen 112) by a non-stylus contact (e.g., contact 728 by finger 202) in the content region (e.g., content region 712) when a drawing tool is selected. In this example, since a drawing tool is selected (e.g., draw affordance 716-a is selected), a mark (e.g., mark 729) is displayed in accordance with movement of contact 728 by finger 202. In some embodiments, when draw affordance 716-a is selected, drawing is enabled on the content region by subsequent inputs, regardless of whether the subsequent inputs are made by a stylus contact or a non-stylus contact.

FIGS. 7N-7O illustrate an example of detecting an input that includes movement across the touch-sensitive display (e.g., touch screen 112) by a stylus contact (e.g., contact 730 by stylus 203) in the content region (e.g., content region 712) when a drawing tool is selected. In some embodiments, while in editing mode (e.g., when second control region 716 is displayed), stylus inputs draw marks regardless of whether a drawing tool is selected. For example, in FIGS. 7C-7D, a drawing tool is not selected (e.g., draw affordance 716-a is not selected) and a mark (e.g., mark 719) is displayed in accordance with movement of contact 718 by stylus 203. In this example, in FIGS. 7N-7O, a drawing tool is selected (e.g., draw affordance 716-a is selected) and a mark (e.g., mark 731) is displayed in accordance with movement of contact 730 by stylus 203. In some embodiments, when movement of the stylus contact is across text, the mark drawn in accordance with movement of the contact is highlighting on the text, as discussed below with respect to FIGS. 7P-7Q. In the example of FIGS. 7N-7O, movement of the stylus contact (e.g., contact 730 by stylus 203) is not across text and the mark (e.g., mark 731) is a line drawn in accordance with movement of the stylus contact.

FIGS. 7P-7Q illustrate an example of detecting an input that includes movement across the touch-sensitive display (e.g., touch screen 112) by a stylus contact (e.g., contact 732 by stylus 203) in the content region (e.g., content region 712) when movement of the stylus contact is across text. In this example, since movement of contact 732 by stylus 203 is across text (e.g., across a number of multiple characters), the mark drawn in accordance with movement of the stylus contact is highlighting on the text (e.g., mark 733 is highlighting the text “The quick brown fox”).

FIG. 7R illustrates an example of detecting an input (e.g., a tap input) in the first control region (e.g., first control region 714) on the edit mode affordance (e.g., edit mode affordance 714-d). In some embodiments, in response to detecting a tap input on edit mode affordance 714-d after editing has occurred, user interface 710 changes from the editing mode (e.g., in FIG. 7Q) to the viewing mode (e.g., in FIG. 7R) and edits made while in the editing mode are saved (e.g., mark 731 and mark 733 are saved). In some embodiments, when user interface 710 changes to the viewing mode (e.g., in FIG. 7R), second control region 716 (e.g., from FIG. 7Q) is no longer displayed. Although in FIG. 7R, the tap input on edit mode affordance 714-d is shown as contact 734 by stylus 203, a non-stylus contact (e.g., by finger 202) on edit mode affordance 714-d would have the same result.

FIGS. 8A-8D are flow diagrams illustrating a method 800 of viewing and editing documents with stylus and finger inputs in accordance with some embodiments. The method 800 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1A) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on or integrated with the display (also called simply a touch-sensitive display). In some embodiments, the display is separate from the touch-sensitive surface. In some embodiments, the device includes one or more sensors to detect signals from a stylus associated with the device. Some operations in method 800 are, optionally, combined and/or the order of some operations is, optionally, changed.

As described below, the method 800 provides an intuitive way to view and edit documents with stylus and finger inputs, allowing simultaneous annotation with stylus inputs and navigation with finger inputs without having to activate a mode-change affordance. The method reduces the number, extent, and/or nature of the inputs from a user when using a stylus and non-stylus to interact with an electronic device, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to enter inputs faster and more efficiently conserves power and increases the time between battery charges.

The device displays (802) a user interface in a viewing mode (e.g., a read-only mode or other mode that does not permit markup or editing of the content) on the touch-sensitive display, the user interface including a content region and a first control region. FIG. 7A, for example, shows user interface 710 in a viewing mode on touch screen 112, user interface 710 including content region 712 and first control region 714. In some embodiments, the first control region includes controls for editing the content. In some embodiments, the first control region includes controls for navigating through the content. In FIG. 7A, for example, first control region 714 includes menu affordance 714-a, deletion affordance 714-b, revert affordance 714-c, edit mode affordance 714-d, and sharing affordance 714-e, as described above with respect to FIG. 7A.

The device, while displaying the user interface in the viewing mode (e.g., in FIG. 7A), detects (804) an input by a first contact on the touch-sensitive display (e.g., touch screen 112). FIG. 7C, for example, shows detecting an input by a stylus contact (e.g., contact 718 by stylus 203) in the content region (e.g., content region 712). As another example, FIG. 7F shows detecting an input by a non-stylus contact (e.g., contact 720 by finger 202) in the content region (e.g., content region 712). As yet another example, FIG. 7H shows detecting an input by a stylus contact (e.g., contact 722 by stylus 203) in the first control region (e.g., first control region 714). As yet another example, FIG. 7I shows detecting an input by a non-stylus contact (e.g., contact 724 by finger 202) in the first control region (e.g., first control region 714).

The device, in response to detecting the input (806), performs a number of operations. In response to detecting the input, in accordance with a determination that the first contact is a stylus contact in the content region (e.g., an input that includes movement across the touch-sensitive display, such as contact 718 by stylus 203 in FIG. 7C), the device changes from the viewing mode (e.g., in FIG. 7A) to an editing mode (e.g., in FIG. 7C), distinct from the viewing mode, that is configured to enable drawing on the content region in the user interface, and the device displays, in the content region, a mark drawn in accordance with movement of the first contact in the input (e.g., a mark based on a path of the input on the touch-sensitive display, such as mark 719 in FIG. 7D). Changing from the viewing mode to the editing mode without having to activate a mode-changing affordance enhances the operability of the device and makes the user-device interface more efficient (e.g., by reducing the number, extent, and/or nature of the inputs from the user and by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently.

In response to detecting the input, in accordance with a determination that the first contact is a non-stylus contact (e.g., a finger contact) in the content region (e.g., an input that includes movement across the touch-sensitive display, such as contact 720 by finger 202 in FIG. 7F), the device remains in the viewing mode (e.g., forgoes changing from the viewing mode to the editing mode), and the device performs a navigation operation in the content region in accordance with movement of the first contact in the input (e.g., performs a scrolling operation or other navigation action in accordance with the input, as shown in FIGS. 7F-7G) without displaying the mark that corresponds to the first contact in the content region (e.g., forgoes displaying the mark). Allowing simultaneous annotation with stylus inputs and navigation with non-stylus inputs without having to activate a mode-change affordance enhances the operability of the device and makes the user-device interface more efficient (e.g., by reducing the number, extent, and/or nature of the inputs from the user and by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently.

In response to detecting the input, in accordance with a determination that the first contact is a stylus contact in the first control region (e.g., a tap input, such as contact 722 by stylus 203 in FIG. 7H), the device performs a control operation. In some embodiments, the control operation includes displaying a second control region (e.g., an editing toolbar) that includes a plurality of controls for the editing mode in response to detecting a tap input on an edit mode affordance (e.g., edit mode affordance 714-d), as shown in FIG. 7H. In some embodiments, the control operation includes deleting a document in response to detecting a tap input on a deletion affordance (e.g., deletion affordance 714-b), sharing a document in response to detecting a tap input on a sharing affordance (e.g., sharing affordance 714-e), displaying a menu for opening a document in response to detecting a tap input on a menu affordance (e.g., menu affordance 714-a), and undoing changes in response to detecting a tap input on a revert affordance (e.g., revert affordance 714-c). Optionally, when the device performs the control operation, the device remains in the viewing mode. In response to detecting the input, in accordance with a determination that the first contact is a non-stylus contact in the first control region (e.g., a tap input, such as contact 724 by finger 202 in FIG. 7I), the device performs the control operation (and optionally, remains in the viewing mode). In FIG. 7I, the control operation includes displaying a second control region (e.g., second control region 716) that includes a plurality of controls for the editing mode in response to detecting a tap input (e.g., contact 724 by finger 202) on an edit mode affordance (e.g., edit mode affordance 714-d). Allowing both stylus inputs and non-stylus inputs to select affordances in the first control region enhances the operability of the device and makes the user-device interface more efficient (e.g., by reducing the number, extent, and/or nature of the inputs from the user and by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently.

In some embodiments, in accordance with a determination that the first contact is the stylus contact in the content region, the mark drawn in accordance with movement of the first contact in the input is displayed (808) without performing the navigation operation. For example, in FIGS. 7C-7D, mark 719 is drawn in accordance with movement of contact 718 by stylus 203 without performing a navigation operation.

In some embodiments, in accordance with a determination that the first contact is the stylus contact in the content region (e.g., an input that includes movement across the touch-sensitive display) (810): in accordance with a determination that movement of the first contact in the input is across text (e.g., across a number of multiple characters, such as movement of contact 732 by stylus 203 in FIG. 7P), the mark drawn in accordance with movement of the first contact is highlighting on the text (e.g., mark 733 in FIG. 7Q); and, in accordance with a determination that movement of the first contact in the input is not across text (e.g., such as movement of contact 730 by stylus 203 in FIG. 7N), the mark drawn in accordance with movement of the first contact in the input is a line drawn in accordance with movement of the first contact in the input (e.g., mark 731 in FIG. 7O). Allowing a stylus input to both highlight text and annotate a document without having to activate an affordance to change drawing tools enhances the operability of the device and makes the user-device interface more efficient (e.g., by reducing the number, extent, and/or nature of the inputs from the user and by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently.

In some embodiments, in accordance with a determination that the first contact is the stylus contact in the content region (e.g., contact 718 by stylus 203 in content region 712, FIG. 7B), the device displays (812) a second control region (e.g., second control region 716), distinct from the first control region (e.g., first control region 714), that includes a plurality of controls for the editing mode. In some embodiments, the second control region (e.g., second control region 716, FIG. 7B) includes one or more tools, such as a drawing tool (e.g., draw affordance 716-a, FIG. 7B) to enable drawing on the content region (where both stylus contacts and non-stylus contacts are enabled to make marks in the content region), a zoom tool (e.g., zoom affordance 716-b, FIG. 7B) to change the magnification of a selected portion of the document, a text tool (e.g., text affordance 716-c, FIG. 7B) to type text in a text box, a signature tool (e.g., signature affordance 716-d, FIG. 7B) to insert a signature into a PDF document, a color tool (e.g., color affordance 716-e, FIG. 7B) to change the color of marks drawn in the content region, a line thickness tool (e.g., thickness affordance 716-f, FIG. 7B) to change the thickness of the marks drawn in the content region, and a font tool (e.g., font affordance 716-g, FIG. 7B) to change the font type, font size, and/or font alignment of text in the document. In some embodiments, in accordance with a determination that the first contact is the non-stylus contact in the content region (e.g., contact 720 by finger 202 in content region 712, FIG. 7E), the device forgoes displaying the second control region, as shown in FIG. 7E.

In some embodiments, in accordance with a determination that the first contact is the stylus contact in the content region, displaying the second control region includes (814) displaying an animation of the second control region appearing on the touch-sensitive display beginning at a time of initial contact of the stylus contact in the content region. In FIG. 7B, for example, second control region 716 is displayed by an animation of second control region 716 appearing on touch screen 112 beginning at a time of initial contact of stylus 203 in content region 712. Fading in the second control region leaves the content region stationary and the stylus contact does not cause changes in the content region other than making marks. This enhances the operability of the device and makes the user-device interface more user-friendly and efficient (e.g., by not distracting the user with a sudden entry into the editing mode, thus helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently.

In some embodiments, in accordance with a determination that the first contact is the non-stylus contact in the first control region (e.g., a tap input) on an edit mode affordance, the device displays (816) the second control region. For example, FIG. 7I shows displaying second control region 716 when the non-stylus contact in the first control region (e.g., contact 724 by finger 202 in first control region 714) is on an edit mode affordance (e.g., edit mode affordance 714-d).

In some embodiments, while displaying the second control region, the device detects (818) a third input by a third contact on the touch-sensitive display; and, in response to detecting the third input: in accordance with a determination that the third contact is a contact in the second control region (e.g., a tap input) on a draw affordance (e.g., selecting a drawing tool), enabling drawing on the content region in the user interface by subsequent inputs, regardless of whether the subsequent inputs are made by a stylus contact or a non-stylus contact. For example, in FIG. 7L, draw affordance 716-a has been selected, so drawing is enabled on content region 712 by subsequent inputs, regardless of whether the subsequent inputs are made by a stylus contact (e.g., contact 730 by stylus 203 in FIGS. 7N-7O) or a non-stylus contact (e.g., contact 728 by finger 202 in FIGS. 7L-7M).

In some embodiments, non-stylus contacts in the content region do not create (820) marks unless the draw affordance is selected. For example, in FIGS. 7J-7K, although second control region 716 is displayed, draw affordance 716-a has not been selected, so the non-stylus contact in the content region (e.g., contact 726 by finger 202 in content region 712) does not create a mark.

In some embodiments, while displaying the user interface in the editing mode, the device detects (822) a second input by a second contact on the touch-sensitive display. The device, in response to detecting the second input, performs a number of operations. In response to detecting the second input, in accordance with a determination that the second contact is a second stylus contact in the content region (e.g., an input that includes movement across the touch-sensitive display): the device displays, in the content region, a second mark drawn in accordance with movement of the second contact in the second input (e.g., a mark based on a path of the second input on the touch-sensitive display). In some embodiments, while displaying the user interface in the editing mode, stylus inputs draw marks without regard to whether a drawing tool is selected. FIGS. 7C-7D, for example, show mark 719 drawn in accordance with movement of contact 718 by stylus 203 where a drawing tool is not selected (e.g., draw affordance 716-a is not selected). FIGS. 7N-7O, for example, show mark 731 drawn in accordance with movement of contact 730 by stylus 203 where a drawing tool is selected (e.g., draw affordance 716-a is selected).

In response to detecting the second input, in accordance with a determination that the second contact is a second non-stylus contact in the content region (e.g., a finger contact of an input that includes movement across the touch-sensitive display): in accordance with a determination that a drawing tool is selected (e.g., from the second control region), the device displays, in the content region, the second mark drawn in accordance with movement of the second contact in the second input. For example, in FIGS. 7L-7M, mark 729 is drawn in accordance with movement of contact 728 by finger 202 when draw affordance 716-a is selected. In some embodiments, when the drawing tool is selected, a stylus input draws and a finger input draws. In response to detecting the second input, in accordance with a determination that the second contact is a second non-stylus contact in the content region (e.g., a finger contact of an input that includes movement across the touch-sensitive display): in accordance with a determination that the drawing tool is not selected, the device forgoes displaying the second mark and optionally, performs a second navigation operation in the content region in accordance with movement of the second contact in the second input (e.g., performing a scrolling operation or other navigation action in accordance with the second input). For example, in FIGS. 7J-7K, contact 726 by finger 202 is detected in content region 712, but draw affordance 716-a is not selected, so no mark is displayed and a navigation operation in accordance with movement of contact 726 by finger 202 is performed. Allowing a non-stylus input to both annotate a document (e.g., when draw affordance 716-a is selected) and navigate in the document (e.g., when draw affordance 716-a is not selected) enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently.

In some embodiments, while displaying the user interface in the editing mode, the device detects (824) a fourth input by a fourth contact on the touch-sensitive display; and, in response to detecting the fourth input: in accordance with a determination that the fourth contact (e.g., stylus contact or non-stylus contact) is in the first control region (e.g., a tap input) on the edit mode affordance: the device changes from the editing mode to the viewing mode; and the device saves edits made while in the editing mode. FIG. 7R, for example, shows a contact (e.g., contact 734) in first control region 714 on edit mode affordance 714-d, and in response, the device changes from the editing mode (e.g., in FIG. 7Q, where second control region 716 is displayed) to the viewing mode (e.g., in FIG. 7R) and edits made while in the editing mode are saved (e.g., mark 731 and mark 733 are saved and displayed in the viewing mode in FIG. 7R).

In some embodiments, the device displays (826) an object with a selection handle in the content region in the editing mode (e.g., a text box added with text affordance 716-c, FIG. 7B). While displaying the object with the selection handle in the content region in the editing mode, the device detects a fifth input by a fifth contact on the touch-sensitive display at a location corresponding to the selection handle. In response to detecting the fifth input: in accordance with a determination that the fifth contact is the non-stylus contact in the content region (e.g., a non-stylus input that includes movement across the touch-sensitive display), the devices moves the selection handle in accordance with movement of the fifth contact in the fifth input (e.g., to move and/or enlarge text boxes in the content region). In some embodiments, non-stylus contacts (e.g., finger contacts) operate selection handles, but stylus contacts do not operate selection handles. Allowing stylus inputs and non-stylus inputs to perform separate functions without having to activate a function-change affordance enhances the operability of the device and makes the user-device interface more efficient (e.g., by reducing the number, extent, and/or nature of the inputs from the user and by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently.

In some embodiments, in response to detecting the fifth input: in accordance with a determination that the fifth contact is the stylus contact in the content region (e.g., a stylus input that includes movement across the touch-sensitive display): the device forgoes (828) moving the selection handle, and the device displays, in the content region, a third mark drawn in accordance with movement of the fifth contact in the fifth input.

It should be understood that the particular order in which the operations in FIGS. 8A-8D have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein.

In accordance with some embodiments, FIG. 9 shows a functional block diagram of an electronic device 900 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, firmware, or a combination thereof to carry out the principles of the various described embodiments.
